Seeing how my phone is a MetroPCS prepaid handset, I had CM7 on my old Optimus M and I never wiped that phone. I left it as is, it ran perfect for 2 years with CM7 so I never changed it. I went in and took out the DSPManager.apk from System\App and the 3 files from System\lib\soundfx copied them to my other phone. Backed up all my original files first of course. Installed the 3 files into System\lib\soundfx and the DSPManager.apk into my System\app folder, then installed the DSPManager.apk from my sd card onto the phone memory. Thoroughly tested for a couple of hours, 100%. No FC's or issues of any kind. So for anyone out there using Metro Handsets this might be a fix if your getting force close problems when trying to install. Files can be downloaded from www.mikesdragonpages.homestead.com/files/DSPMetro.zip.
